## forbidden
- Mixing icon libraries
- rgba()
- `<style>`, `class`, `<foreignObject>`, `textPath`, `@font-face`, `<animate*>`, `<script>`, `<iframe>`, `<symbol>`+`<use>`
- `<g opacity>` (set opacity on each child element individually)
- HTML named entities in text — write as raw Unicode; XML reserved chars must be escaped as `&amp; &lt; &gt; &quot; &apos;`
- Rounded corners (rx > 0) — except inside `simple-icons` brand glyphs
- Linear/radial gradients — pure flat color only
- Drop shadows / filter effects
